BU RN ER-CARRIAGE FOR GAS-FURNACES.

SPECIFICATION forming part of Letters Patent No. 409,625, dated August20, 1889.

Application iilefl Apri111,1889. Serial No. 306 ,798. (No model.)

To all whom, t may concern:

Be it known that I, HAROLD J. BELL, a citizen of the United States,residing at Gloucester City, in the county of Camden and State of NewJersey, have invented new and useful Improvements in Burner-Carriagesfor GasfIihunaces, of which the following` is a specification.

This invention relates to a burner-carriage for gas-burners adapted forheating boilers and furnaces by the combustion of gas; and it consistsin the construction and combination of parts, as hereinafter described,Whereby said burners can be moved into and outv of thecombustion-chamber of a furnace, or

be rolled into position beneath a steam-boiler, or be withdrawn withease, whenever required, thus facilitating repairs or cleaning of theburners when needed.

The invention is illustrated in the annexed drawings, in whicht Figurelrepresents in perspective and partly in section a steam-boiler with myburnercarriage in position beneath the boiler, one side of thefurnace-wall bein g partly removed; and Fig. 2 is a sectional detail.

Referring to the drawings, the numeral 1 designates a steam-boiler, and2 the furnacewalls. On the inner sides of the side furnace- Walls areledges 3, that support railway-rails 4 for the Wheels 5 of aburner-carriage 6, on which the air chamber or conduit 7, the gaschamber or conduit 8, and the attached blowpipe burners 9 are-support-ed. Vhen used with a cylindrical steam-boiler, as shown, theair and gas chambers 7 and 8 may be composed of parallel metal plates10, curved to correspond to the curvature of the boiler, said platesbeing arranged at a suitable distance apart to form chambers or conduitsof the desired capacity, which chambers are closed at their ends andsides by suitable metal strips. The plates 10 may be braced by tubularstays 11 and securely connected, as shown in an application filed by meFebruary S, 1888, Serial No. 299,168, in which application I havedescribed and claimed a preferred form of gas-burner. Instead, however,of solid bolts, as shown in said application, I prefer to connect theplates 10 by means of sleeves or tubular bolts 12, Fig. 2, which willpermit the passage of sufficient air to carry off the products ofcombustion. The air chamber or conduit 7 and gas chamber or conduit 8may be extended the entire length of the boiler, and may be curvedupward at the sides any suitable or convenient distance. Air and gas areto be supplied to these chambers 7 and 8 at any point through suitablepipes, (not shown,) and these pipes should be so connected with the airand gas chambers or be provided with joints and cocks of suchconstruction as will permit their being disconnected from said chambersto enable the burner-carriage to be withdrawn from the furnace or frombeneath the boiler whenever desired. The outer or main portion of thegas-burner 9 communicates with the gas conduit or chamber S, and eachburner is provided with a central air-tube 13, that communicates withthe air chamber or conduit 7, thus providing each burner with a centraljet of air. If preferred, however, the air-conduit may be used for thepassage of gas, and the gas-conduit may be used as an air-passage. Theburners 9 are distributed at intervals to effect a thorough heating ofthe furnace or boiler, as the case may be, the

.invention being` adapted not only to the heating of steam-boilers, butfor usev in various kinds of furnaces and combustion-chambers as Well.

It is obvious that the gas and air chambers, instead of being curved, asshown, may be straight and be arranged in any suitable position,according to the form of furnace.

Whenever it is necessary to examine the condition of the burners, or torepair or clean them, or make repairs in the boiler or in thecombustion-chamber, the burner-carriage G can be readily withdrawn alongthe rails 4, thereby giving direct. access to the burners and connectedgas and air chambers, as well as to the combustion-chamber of thefurnace.

Vhat I claim as my invention is- 1. The combination, with a gas-burnercarriage, of separate gas and air chambers supported on said carriage,and comprising horizontal plates connected by bolts, and blowpipegas-burners supported by and communi- IOO eating With said chambers,substantially as eating with Said chambers, substantially as 1odescribed. described.
